Elmhurst Memorial said that, last fall, it announced that it would be discontinuing some services, including some inpatient behavioral health programs and food services, at its Berteau campus in 2012 as part of its plan to redevelop that area, primarily for senior-living services.

As a result, it's closing some services on the site, resulting in the layoffs. It said it's trying to find new positions for the affected workers.

"It is anticipated that several employees will be retained by the health system," a spokeswoman said. Others have been offered outplacement services, and Elmhurst Memorial is also working with the DuPage County Workforce Development Division to help laid-off workers. Elmhurst Memorial also said it'll work with other area health providers to ensure continued access to services that it's discontinuing on the Berteau campus.

The Illinois Department of Commerce and Economic Opportunity requires employers to provide 60 days' notice of plant closures or mass layoffs. The law applies to businesses with at least 75 full-time workers.

A mass layoff occurs at a single site of employment resulting in job losses during any 30-day period of at least a third of employees and at least 25 employees, or at least 250 employees regardless of the percentage.
